IBM Worklight V6.0 Mobile Application Development Sample Questions:

1. A mobile application developer has written a hybrid android app and has enabled Push Notifications for it. On subscribing to the eventsource with userId "TestUser", the userID that is persisted in the database is "3266532456798262364265" instead of "TestUser". What is the cause? A security test is missing from the:

A) application-descriptor.xml.
B) WL.Server.createEventSource function.
C) adapter methods.
D) adapter methods and the application.

2. A mobile application developer has a business requirement that data be encrypted while at rest on the mobile device. As data is stored in the encrypted cache, the application developer starts seeing strange behavior and cannot find this behavior in the documentation. What is the cause of the strange behavior?

A) The credentials used to open the cache are invalid.
B) The AES 256-bit encryption key is corrupt.
C) The encrypted cache has exceeded the 5 Mb limit.
D) The encrypted cache is closed.

3. A mobile application developer needs to create an application for a hospital that will only allow a doctor access to medical records while inside the hospital. How can the mobile application developer accomplish this task using Worklight APIs?

A) On the device, use WL.Client.isInsidePolygon() to determine if the doctor is in the hospital, then use WL.Server.setUserRealm() toallow or restrict access.
B) On the device, use a PositionChange trigger to signal when the user moves into a different area, then use WL.Server.setUserRealm() toto allow or restrict access.
C) Within an adapter, add event listeners WL.Events.GEOFENCE_ENTER and WL.Events.GEOFENCE_EXIT so a callback sets a variable whenevera doctor moves in or out of the geofence. Check the variable when the adapter is called to determine if the doctor is in an authorized location. Ifnot, do not process further.
D) Within an adapter, use WL.Server.getClientDeviceContext() to determine if the doctor is in an authorized location. If not, do not processfurther.

4. A mobile application developer is made aware of a possible error in the JavaScript code that could expose a customer's user id and password on one platform. The application developer begins to work on a fix to the code. Which capability should the application developer ask the administrator to use that blocks users of that platform from accessing the server until the fix can be installed?

A) Use direct update to disable the application.
B) Use application authenticity to block access.
C) Use remote application notification.
D) Use remote application disable.

5. A mobile application developer has completed testing a new SQL adapter locally in Worklight Studio. Now the application developer is configuring the adapter for a test server. What modification does the application developer need to make to the adapter configuration prior to deployment on the test server?

A) None
B) Modify the Host name in the server.xml file.
C) Modify the Host name in the adapter's XML file.
D) Modify the Host name in worklight.properties file.
